Which of the following is a potent source of omega-3 fatty acids that can be found in both solid and oil form?

Flaxseed is recognized as a potent source of omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which is essential for heart health and overall well-being. It contains high levels of these fatty acids both in its whole form and as flaxseed oil, which provides a concentrated source of ALA. This versatility allows consumers to incorporate it into their diets easily, whether by adding ground flaxseed to smoothies, cereals, or baked goods, or by using flaxseed oil in dressings and marinades.

In contrast, the other options do not have significant amounts of omega-3 fatty acids. Olive oil primarily contains monounsaturated fats, specifically oleic acid, which while healthy, does not provide the omega-3s that are important for anti-inflammatory processes. Peanut butter, primarily made from peanuts, is a good source of protein and monounsaturated fats but lacks substantial omega-3 content. Safflower oil is mainly composed of polyunsaturated fats, particularly omega-6 fatty acids, with negligible omega-3 content. Therefore, flaxseed stands out distinctly as the best source of omega-3s among the choices given.
